Newcastle United were comfortable 3-0 winners over Cardiff City on Saturday.
Fabian Schar scored a double for Newcastle, with Ayoze Perez making it three in stoppage time.
Rafa Benitez hopes his side can continue their fine form and feels that with a similar commitment in the next few weeks his side can succeed.
He said: "I think so.
"We were talking about how important this game could be, but as I said before, we will have a lot of games against teams that are close to us and these are the key games when you can play well and you can win, or even without playing well, you can get something.
"Today we did it, we played well, we had a lot of energy and commitment from everyone and it was crucial.
"I think the fans appreciate that and hopefully we will stick together until the end and as I have said many times, we will have more chances to stay up."
